C18-22 Hydroxyalkyl Hydroxypropyl Guar is a modified guar gum derivative used in skincare and haircare to thicken formulations, stabilize emulsions, and impart a smooth, conditioned feel to skin and hair. It functions as a non-active formulation aid rather than a therapeutic active.
| Reported effect | How often | Notes |
|---|---|---|
Mild skin irritation | Rare | Occasional transient redness or stinging, usually related to overall formulation rather than the ingredient alone. |
Allergic contact dermatitis | Very rare | Sensitization to guar-derived polymers is uncommon but has been occasionally reported. |
Eye irritation | Rare | Possible mild irritation if products containing it accidentally enter the eyes. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
